1. Icyuma nyamukuru cya selile ether
Mugutezimbere kwitegura, ether ether ninyongera nyamukuru yongewe mumafaranga make cyane ariko irashobora kunoza imikorere minisiteri itose kandi bigira ingaruka kubikorwa byubwubatsi bya minisiteri.
2. Ubwoko bwa selire
Gukora ubumwe bwa selile bigizwe ahanini ni fibre karemano binyuze muri alkali, gutsimbarara (guhuza, gukaraba, gusya, gusya nibindi bikorwa nibindi.
Dukurikije ibikoresho by'ibanze bibisi, fibre karemano irashobora kugabanywamo muri: Ipamba isanzwe, Beech Fibre, n'ibindi. Impamyabumenyi zabo za Poly nini iratandukanye, igira ingaruka ku rugero rwa nyuma rw'ibicuruzwa byabo. Kugeza ubu, abakora selile bakomeye bakoresha fibre ya pamba (kubicuruzwa bya Nitrocellse) nkibikoresho nyamukuru byibanze.
Abakoresha Cellulose barashobora kugabanamo ionic na nonine. Ubwoko bwa ionic burimo imodoka ya selile
Kugeza ubu, abahanga muri selile bakoresheje umuryango witeguye cyane cyane ni methyl selile (MC), Methyl HydroxyIjorol Muri minisiteri yiteguye, kubera ko selile ya selile (Carboxymethyl umunyu wa selile) nta gaciro gakoreshwa mu bicuruzwa byiteguye gukoresha sima, bitandukanijwe na lime, n'ibindi. Ahantu hamwe mu Bushinwa, Carboxymethyl, Umunyu wa Cellulose ukoreshwa nkuwabyimbye kubicuruzwa bimwe byimbere byatunganijwe hamwe nibikoresho nyamukuru byahinduwe hamwe na Shungfei nkiyungurura. Iki gicuruzwa kiremereye cyoroshye kandi ntigihanganira amazi, kandi ubu ni cyigishwa. Hydroxyyethyl selile irakoreshwa no mu bicuruzwa bimwe byiteguye, ariko bifite umugabane muto w'isoko.
3. Ibipimo nyamukuru bifatika bya selile
(1) Kudakemurwa
Cellulose ni Polyhydroxy Colymer yuzuyemo ko atagusenya cyangwa ngo ashongeshe. Nyuma yo gutora, selile irashonga mumazi, shyiramo igisubizo cya alkali na organic olvent, kandi bifite thermoplastity. Kukesha cyane cyane biterwa nibintu bine: Icyambere, kwikebagura biratandukanye na viscosiya, hepfo ya virusire, niko kwitonda. Icya kabiri, ibiranga amatsinda byatangijwe muburyo bwo guhindura, niko itsinda ryatangiriye, hepfo kwikeba; Polori nyinshi itsinda ryatangije, byoroshye ether ya selile ni ugushonga mumazi. Icya gatatu, urwego rwo gusimburwa no gukwirakwiza amatsinda ashimishijwe muri Macronolecules. Abakoresha benshi ba selile barashobora gushonga gusa mumazi munsi yurwego runaka rwo gusimburwa. Kane, urwego rwamasatsi ya selile ether, urwego rwo hejuru rwa polymerizira, ntirushomanze; urwego rwo hasi rwa polymerizira, ubwinini bwagutse kurwego rwo gusimburwa bushobora gushonga mumazi.
(2) Kugumana amazi
Kugumana amazi nigikorwa cyingenzi cya selile, kandi nigikorwa nacyo cyinshi cyumye ifu yumye, cyane cyane izo mu turere two mu majyepfo, witondere. Ibintu bireba ingaruka zo kugumana amazi zirimo umubare wa selile ether yongeyeho, viscosiya, ubushyuhe bwubushyuhe bwo gukoresha ibidukikije. Umubare munini wa selile Ether yongeyeho, ingaruka nziza y'amazi; Ikomeye ya virusire, ingaruka nziza zo kugumana amazi; Ibice byiza, ingaruka nziza yo kugumana amazi.
(3) vicosity
Viscozetity nikigeragezo cyingenzi cyibicuruzwa bya selile. Kugeza ubu, abakora selile batandukanye ba Ether bakoresha uburyo n'ibikoresho bitandukanye kugirango bapime vicosiya. Kubicuruzwa bimwe, ibisubizo bya viscosity byapimwe nuburyo butandukanye buratandukanye cyane, ndetse bamwe ndetse banatandukanije kabiri. Kubwibyo, mugihe ugereranya vicosi, bigomba gukorwa hagati yuburyo bumwe bwikizamini, harimo ubushyuhe, rotor, nibindi.
Muri rusange, hejuru cyane viscosiya, ingaruka nziza zo kugumana amazi. Ariko, hejurus viscosiya, hejuru yuburemere bwa kalliolose, hamwe no kugabana bihuye nibyokundwa bizagira ingaruka mbi ku mbaraga nubwubatsi bwa minisiteri. Hejuru ya virusire, uko byanze bikunze ingaruka kuri minisiteri, ariko ntabwo bigereranyije neza. Iy'isumbuye rya virusire, urujijo cyane minisiteri itose. Mugihe cyo kubaka, bigaragarira nko kwizirika ku gisicraper no gufunga cyane. Ariko ntabwo ari byiza kongera imbaraga zuburyo bwa minisiteri itose. Mugihe cyo kubaka, imikorere yo kurwanya sag iragaragara. Ibinyuranye nibyo, bamwe mu rubyiruko no hasi ariko bahinduwe Methyl bahanganye na Methyl bafite imikorere myiza mugutezimbere imbaraga zubuntu bwa minisiteri itose.
(4) ibyiza by'ibice:
Ubugari bwa Cellulose bwakoreshejwe mu miburo yiteguye kuba ifu isabwa kuba ifu, hamwe n'amazi make, kandi igorofa nayo isaba 20% kugeza munsi ya 63 μm. Ibyiza bigira ingaruka ku kuntu gukira kwa selile. Ubusanzwe abakoresha ubugari bwa selire basanzwe muburyo bwa granules, biroroshye gutatana no gushonga mumazi nta nkunga yiteguye, nuko badakwiriye gukoreshwa muri minisiteri yiteguye (ntabwo rero ibicuruzwa byo murugo ari floccuront, Ntabwo byoroshye gutatana no gushonga mumazi, no gukunda kuri caking). Mu kwitegura kuri minisiteri ivanze, ether ether ikwirakwizwa hagati ya aggrerget, filile nziza na sima nibindi bikoresho byashizweho. Gusa ifu ihagije irashobora kwirinda selile ether agglomeration mugihe uvanze namazi. Iyo ubumwe bwa selile yongeweho amazi kugirango ashongeje agglomeration, biragoye cyane gutatana no gushonga.
(5) guhindura selile ether
Guhinduranya ubumwe bwa selile ni kwagura imikorere yacyo, kandi nigice cyingenzi. Umutungo wa selile urashobora kunozwa kugirango utezimbere ubuvuzi bwayo, kudacogora, kuganduka, kubyimba, kugumana amazi hamwe nibibazo bya firime, kimwe namashusho yamavuta.
4. Ingaruka z'ubushyuhe nyaburanga ku kugumana amazi ya minisiteri
Kugumana amazi ya selile bigabanuka hamwe no kwiyongera k'ubushyuhe. Mubikorwa bifatika, minisiteri ikunze gukoreshwa kubushyuhe bushyushye ku bushyuhe bwinshi (hejuru ya 40 ° C) mubidukikije byinshi. Igitonyanga cyo gusubizwa amazi cyavuyemo ingaruka zigaragara ku kazi no kurwanya. Kwishingikiriza ku bushyuhe buzakomeza kuganisha ku gucika intege kwa minisiteri imitungo, kandi birakomeye cyane kugirango bigabanye ingaruka z'ubushyuhe muri iyi miterere. Udukoryo twa mirtar ryahinduwe muburyo bukwiye, kandi impinduka nyinshi zingenzi zakozwe mubyakoreshejwe. Nubwo kongera dosiye (formula yimpeshyi), ibikorwa no kurwanya ibikorwa biracyashobora guhabwa imikoreshereze idasanzwe ya selile, nko kongera ubushobozi bwihariye, nibindi, kugirango ingaruka zingamiro zishobore kugerwaho ku bushyuhe bwinshi. Ikomeza ingaruka nziza iyo iri hejuru, kugirango itanga imikorere myiza mubihe bibi.
5. Gusaba MIRTER YITEGURA
Mugutezimbere kuri minisiteri ivanze, Ether Sohese akina uruhare rwo kugumana amazi, kubyimba no kunoza imikorere yubwubatsi. Imikorere myiza yo kugumana amazi yemeza ko minisiteri itazatera amande, igabanuka n'imbaraga zo kugabanya imbaraga zamazi kandi hakurya. Ingaruka zingana zongera cyane imbaraga zuburyo bwa minisiteri itose. Hiyongereyeho ubumwe bwa selile irashobora kunoza cyane visiteri itose, kandi ifite ubuyobe bwiza kubice bitandukanye, bityo bigatuma urukuta rwimikorere ya minisiteri itose no kugabanya imyanda. Mubyongeyeho, uruhare rwa selile ether mubicuruzwa bitandukanye nabyo biratandukanye. Kurugero, muri tile ashimishijwe, ether elile irashobora kongera igihe cyo gufungura no guhindura igihe; Mu buryo bwa mashini butera minisiteri, irashobora kunoza imbaraga za minisiteri itose; Kwigereranya, irashobora gukumira gutura, gutandukanya no kudahaza. Kubwibyo, nkibikongo byingenzi, ether ya selile ikoreshwa cyane mumashanyarazi yumye.
